This new system represents an ultracompact configuration of radius R_S = 2M whose interior metric can be matched smoothly to a conformally deformed Schwarcschild exterior. Remarkably, the model satisfies some of the basic requirements to describe a physically acceptable stellar model, such as a positive density everywhere and decreasing monotonously from the centre, as well as a non-uniform and monotonic pressure.
